When ON, curves are exported.
If an Alias layer has symmetry ON, this information and the geometric objects resulting from the layer’s symmetry can be Merged and converted or left intact (Unmerged) and converted.
When off layer symmetry is not exported.
Tesselation
When the tessellator is set to Fast, models are triangulated more quickly and less accurately. When the tessellator is set to Accurate, models are triangulated more accurately and slowly.
The value specifies the amount the polygonal surface can deviate from the original NURBS surface.The default value is 0.01.
If checked, a Max edge length slider appears to control how large the triangles can get. If unchecked, there is no limit on the size of the triangles.
Specifies the maximum length of any triangle edge (in current linear units).
